MANUFACTURE OF SOAP IN CAKE FORM.

Application filed August 2, 1924. Serial No. 729,825.

This invention relates to the manufacture of soap and more particularlyto the manufacture of soap for toilet purposes. Heretofore it has beencustomary to provide a cake of soap of one colour and permeated with asingle perfume. The present invention has for its object a process forthe manufacture of soap, more especially toilet soap preferably shewinga plurality of colours and having one or more than one perfumepermeating the cake of soap as a whole.

Soaps have already been produced which shew several different coloursbut in these soaps the variegated nature of the soap has generally beenobtained by embedding small pieces of soap in a mass of soap as a whole.The variegated nature of the resultant soap is inferior and does notextend throughout the entire mass of soap. For example, the colouredlayers of soap alternate with the white layers of soap so that thevariegated nature, of the soap does not extend homogeneously through theentire mass of the soap. Besides, this method of production has thedisadvantage that the cake of soap when in use splits up into pieces dueto the fact that thelayers are not completely secured throughout. Theexisting corners and edges are unsuitable for handling and are alsodisagreeable to the touch and the crumbling of the soap into severalparts is accompanied by considerable waste.

The present invention avoids these disadvantages by reason-ofthe factthat a homogeneous cake of soap is"'produced. The process of the presentinvention is extremely simple to carry out. It consists conveniently inthat the soap in powdered form coloured and perfumed in known manner isseparately assembled in juxtaposition according to the different kindsand disposed in a I press. The press is provided with partition walls ora mold which are inserted therein before filling in the soap, thevarious quan tities of the coloured and perfumed soap being filled inthereafter. After filling in the several quantities of soap, thepartition walls are remo'vedso that the several quantities of colouredand powdered soap, although lying directly adjacent each other, arequite separate. The soap is now subjected to pressure in a manner whichis well known and combined to form an insoluble whole at which stage inthe process the cake of soap is complete. After having been subjected topressure the differently coloured parts of the soap remain separate fromone another without oo-mingling or. runnin one into the other which, ifsuch did taEe place, would produce a badly coloured and obnoxiouslysmelling soap.

In soaps produced in accordance with the present invention the colouredportions of the soap extend throughout the entire mass and the perfumeor perfumes likewise extend throughout the mass of the soap or theindividual parts of which the soap 1s made. Such soaps are pleasing tothe eye and besides soaps can be produced which, by reason of the mixedarrangement of the differently coloured soap parts, have the appearanceand also the fragrance of a nosegay. Enumerable arrangements of thecoloured soap pieces may be made without limit.

The main advantage of soap produced in accordance with the presentinvention consists in that it does not lose its scent or colour afterbeing used once, but such colour and scent persist until the entire cakeof soap has been used up, and when in use an agreeable fragrance isproduced. In fact. according to the nature of the colour and the methodof arranging the various coloured parts of the soap in the mass as awhole, a gradual change in the perfume can be produced as the soapdiminishes by use. soap parts may be arranged in stratified layers.

It is already known to mix or blend several perfumes and to perfume thesoa with thescent thus obtained, but in suc case the perfumes applied tothe soap are. individually and separately imperceptible in the finishedcake of soap because there is produced a new definite scent whereby afragrance is obtained having the same effect as that which can beperceived from a nosegay composed of different fragrant flowers.

In order that the invention may be clearly understood reference is madeto the accompanying drawing which shews several constructions by way ofexample in accordance with the present invention.

Figure 1 is a perspective View shewing a cake of soap in which thedifferently colon red and perfumed parts a, (z? of the soap arejuxtaposed.

Figure 2 is a perspective view shewing a cake of soap in which thepowdered soap is superimposed in two layers a, a

For example, the diiferently coloured I Figure 3 is a perspective viewhewing a cake of soap in which three different layers a, a a are used.

Figure 4 is a perspective view of a cake of soap in which thedifferently coloured and perfumed parts a, a which extend through theentire mass are assembled to form a homogenous cake of soap.

Any desired number of colours may be used as well as any desired numberof perfumes and the parts (1 a may be arranged in any suitable anddesired manner. Further, the exterior form of the cake of soap as awhole may be of any suitable and convenient form and if desireddifferently coloured pieces of soap may be assembled to form one cakehaving only one perfume or a plurality of perfumes, that is to say, oneperfume for each individual and differently coloured piece of soap whichis incorporated in the mass. Conversely similarly coloured pieces ofsoap may be used with different kinds of perfumes or similarly colouredpieces of soap may be used with one perfume. Having now particularlydescribed and ascertained the nature of my said invention and in whatmanner the same is to be performed, I declare that what I claim is 1.. Aprocess of manufacturing cakes of soap from differently colored soappowders which comprises the steps of filling a mold with differentlycolored soap powders and arranging the powders horizontally side by sideto correspond to the desired color design; and then compressing saidpowders together to produce a homogeneous body in cake form in which thedifferently colored portions are integral with each other.

2. A process of manufacturing cakes of soap from differently coloredsoap powders, which comprises the steps of arranging a plurality ofpartitions to provide spaces conforming to the required design; fillingeach space with a colored soap powder; re moving said partitions; andthen compressing said powders together to produce a homogeneous body incake form in which the differently colored portions are integral witheach other. 7

3. A process of manufacturing cakes of soap from differently coloredsoap powders which comprises the steps of filling a parti tioned mold,having the required design therein, with colored soap powders; removingthe mold; and then compressing said powders together to produce ahomogeneous body in cake form in which the differently colored portionsare integral with each other and extend through the entire cake.

4. A process of manufacturing cakes of soap from colored soap powders,which comprises the steps of arranging a plurality of partitions toconform to the required de sign; filling the spaces on both sides ofthe' partitions with differently colored soa powders; removing saidpartitions; an then compressing said powders to produce a homogeneousbody in cake form in which the difi'erently colored portions areintegral with each other.
